When the dump station is just out of reach, the Camco RhinoFLEX Extension Kit (part 39764 / 11-0019) gives you an extra 10 feet of heavy-duty, steel-reinforced sewer hose. Compatible with any sewer hose that uses a standard bayonet fitting -- not just RhinoFLEX -- so it works across virtually all modern RV setups.
Not every campground or dump station is laid out conveniently, and running short on hose length is one of the most frustrating moments of any RV trip. The RhinoFLEX 10-foot extension solves that problem cleanly: connect it to your existing hose using the built-in swivel lug and bayonet fitting, lock it in place with the included locking rings, and you are ready to dump.
The hose is constructed from 23-mil polyolefin reinforced with a steel wire helix -- the same proven construction as the full RhinoFLEX product line. That steel wire keeps the hose from kinking or collapsing under its own weight when extended across uneven ground, a common failure point on cheaper extensions.
Polyolefin walls reinforced with a steel wire helix resist kinking, crushing, and collapse -- even on uneven terrain or longer unsupported runs.
End fittings are molded from UV-stabilized resin so they won't crack, yellow, or become brittle after seasons of outdoor storage and sun exposure.
Two locking rings are included and designed to be removed and reused if you transfer the fittings to a new hose -- saving money and reducing waste over time.
Works with any RV sewer hose equipped with a standard bayonet fitting -- including other RhinoFLEX kits, Rhino 5-in-1, and most aftermarket hose sets.
This kit is designed specifically as an extension, not a standalone replacement. Your existing hose kit's elbow or sewer inlet adapter stays in place at the dump station end; the extension adds length between your coach's sewer outlet and the rest of your hose run. For most RVers, one 10-foot extension is enough to bridge the gap at sites with awkward hookup positions.
If you regularly camp at sites where the hookup is farther away, Camco also offers 20-foot extension kits and complete RhinoFLEX starter kits with additional hardware.
This extension is ideal for full-timers and frequent travelers who have encountered short-reach situations at state parks, private campgrounds, or rest-area dump stations. It is also a smart addition for anyone upgrading from a starter 10-foot kit to a longer total run without buying an entirely new hose set.
